- Add exponential backoff retry to DuckDuckGo adapter (3 attempts with
jitter) to handle transient rate-limiting and connection errors.
- Add native fetch() fallback in WebFetch when axios hangs with custom
DNS lookup in bundled contexts.
- Prevent broken native-path fallback for web search on OpenAI shim
providers (minimax, moonshot, nvidia-nim, etc.) that do not support
Anthropic's web_search_20250305 tool.
- Cherry-pick existing fixes:
- a48bd56: cover codex/minimax/nvidia-nim in getSmallFastModel()
- 31f0b68: 45s budget + raw-markdown fallback for secondary model
- 446c1e8: sparse Codex /responses payload parsing
- ae3f0b2: echo reasoning_content on assistant tool-call messages
- Fix domainCheck.test.ts mock modules to include isFirstPartyAnthropicBaseUrl
and isGithubNativeAnthropicMode exports.

getUserSpecifiedModelSetting() decides which env var to consult based on
the active provider. The check included openai and github but omitted
codex, nvidia-nim, and minimax — even though all three use the OpenAI
shim transport and get their model routing via CLAUDE_CODE_USE_OPENAI=1
+ OPENAI_MODEL (set by applyProviderProfileToProcessEnv).
Concrete failure: user switches from Moonshot profile (which persisted
settings.model='kimi-k2.6') to the Codex profile. The new profile
correctly writes OPENAI_MODEL=codexplan + base URL to
chatgpt.com/backend-api/codex. Startup banner reflects Codex / gpt-5.4
correctly. But at request time getUserSpecifiedModelSetting() returns
early for provider='codex' (not in the env-consult list), falls through
to the stale settings.model='kimi-k2.6', and the Codex API rejects:
API Error 400: "The 'kimi-k2.6' model is not supported when using
Codex with a ChatGPT account."
Fix: extract an isOpenAIShimProvider flag covering openai|codex|github|
nvidia-nim|minimax — all providers that set OPENAI_MODEL as their model
env var. The Gemini and Mistral branches stay as-is (they use
GEMINI_MODEL / MISTRAL_MODEL).
Five regression tests pin the fix for each OpenAI-shim provider plus
guard tests for openai and github that already worked.
